Abstract: The paper presents a distance-based inverse deduction algorithm for site data based on distance-based process algorithm and long-flag hashing algorithm. For giving two parameters, any input point on site data line and relative distance from it, it can get corresponding output point in the way of judging the segmentation and the region divided by long-flag inside the segmentation in both of which it locates to calculate the distance parameters from the output point to the region logic start point. Namely, users can get the output point automatically by the input point and its relative distance without any additional configuration so as to extend the site data process functionalities. The paper also looks forward to the algorithm’s detail application and plan for site data.
